MACHINE FOR PLACING SPRINGS IN FABRIC JPOCKIETS.

Application tiled. may 9,

This invention relates to machines for making coiled springs andplacing-same in pockets of fabric" strips.

One object of the invention is to co-ordinate a spring coiling devicewith mechanisms for filling fabric pockets with springs, and with springfastening means, whereby a strip of fabric having a plurality ofadjacent pocket sections may be rapidly and the springs secured withinthe pockets.

Another object is to accomplish this result by mechanism which shall,practically speaking, be automatic as well as continuous in operation.

To the accomplishment of these objects, the invention consists in thedevices and combinations of devices illustrated in the accompanyingdrawingsand herein described; and more particularly pointed out in thesubjoined claims.

These and other objects and advantages may be accomplished by meanswhich may be generally described as follows:

A strip of suitable fabric, such for example as burlap, is fedcontinuously into and through the machine, being first foldedlongitudinally between its sides into U-shape, with the two lapssuperposed, The marginal portion of each lap is inturned. ll prefer touse a plurality of fabric partition members secured. preferably, bystitching, in spaced apart relation to the top and bottom layers of thefabric strip, thus forming a'plurality of pockets lengthwise of thestrip.

Wire is fed continuously through a suitable coiling device, to form ahelical or spiral spring, and as each spring is formed, the wire issevered, permitting the completed spring to pass into a funnel and thendownwardly into a hollow frame to a reciprocating member which travelsin the horizontal plane of the folded fabric strip. Each spring iscompressed, while in the hollow frame, by a pair of compresor arms. theflanges of which a e caused to enter the hollow frame or tube d engagethe spring. The tube has diametrically opposite slots for this purpose,whichl permit the compressor arm flange to rest upon the severed, coiledspring and'when the arm flanges are automatically caused to movedownwardly through these slots, they push thespring through'the tubularmember andcompress the spring so that the reciprocating member, whichoperates as soon as the spring 15 compressed and positloned opposite itsend,

filled with springs pair of stapling rear. $er1a1 No. wane.

may push the compressed sprin or spread apart folds of the fa pair ofpivoted jaws are the top and bottom layers of the tance, i. e.,sufficiently to bring a pocket space into position to receive the nextcompressed spring. When these jaws are opened and returned to repeatthis operation, the released spring will expand quickly, spreading apartthe top and bottom layers of the fabric the proper distance,a part ofthe top and bottom volutcs of the spring at the same time entering thesmall pocket-recess formed between the inturned marginal parts of thefabricand the top and bottom layers, respec tively, thereof.

As the fabric strip continues to be moved by the gripping jaws, throughthe machine, the part or pocket section thus filled with springs ispassed over a conveyor through a devices, the first one passing a staplethrough the top of the strip to secure one end coil or volute of thespring to the fabric, and the second one stapling the other end coil orvolute in the other pocketrecess formed by the inturning of the othermargin of the strip.

The various parts are synchronized so that the fabric may issue from themachine with substantially a step bystep or intermittent movement, thecompleted striphaving a'pluand having a coiled spring in.

he'fabm'a striplhe pocketed strip A the spring S in a familiar manner.

will be fed into one side of the machine in any convenient manner, asfrom a reel, or other source of supply, and will emerge from the otherside of the machine with a spring in each pocket as shown in Figures 4and 20.

The strip of fabric, such as burlap, or the like, indicated as a wholeby the letter A, is moved in the direction indicated by the arrows inFigures 3 or 4. This strip is folded longitudinally, as at 1, intoU-shape, to have an upper layer or fold 2 and a lower layer or fold 3.The outer margins of the strip are folded as shown at 4 and 5 and formtwo longitudinally extending parts which are inwardly turned against thelayers 2 and 3, respectively. When this strip is completed into pocketedform it will assume the appearance indicated on Figure 20. A portion ofthe top layer 2 and a portion of the bottom layer 3 will constitute thetop and bottom, respectively, of the pocket, and the folded portion 1and the adjacent portions of the top and bottom layers 2 and 3, willconstitute a back (3. Usually I prefer to separate the top and thebottom layers 2 and 3 by transversely positioned, spaced apart,partition strips 7 of similar fabric, the ends of the partition 7 beingsecured to the top and bottom 2 and 3, respectively, by transverse linesof stitching or other suitable means. These partitions 7, when used.will form the two sides of each pocket which, as shown, is arectangularly shaped pocket having an open face. A spring S ispositioned in each pocket, a part of the upper and lower volute or coilof the spring 100 entering the space between the inturned portions 4 and5 and the top and bottom portions 2 and 3, respectively, of the fabric,and being secured therein in any suitable manner, but preferably bymeans of staples 8.

The mechanism.-Referring now more particularly to Figures 1234, themajor portion of the mechanism illustrated is suitably mounted upon aframe B, having a base 9, and carrying in suitable bearings an op- 1mcrating shaft 10, which shaft is actuated by any suitable motive power,as for example from a belt 11 over pulleys 12 mounted upon the shaft 10.

The frame B is provided with a forwardly 116 extending table 13, mountedupon which is a vertically extending tube T secured by a bracket 14.Removably positioned upon the upper end of the tube T is a curved,hollow funnel 15 adapted to receive a spring S. A 12 suitable springcoiler of any conventional type is designated as a whole by the letterC, said device being adapted to receive spring wire 16 from any sourceof supply and by means of a coiler head 17 convert the wire iInto hespring coiler C, per se, being no part of the present invention, exceptin combination as a whole with co-operating parts of the machine, neednot be further described. When tween them.

Fabric fold spmadn-Mountcd upon the end of the table 13 and extendingwithin the path of the moving folded fabric strip A, is.

a hollow spreader block 19 of an interior diameter sufficiently large topermit of the coiled spring S, when compressed, to be pushedtherethrough. The two folds 2 and 3 of the oncoming fabric strip rideover the top and below the bottom of the spreader block 19, 'as will beunderstood by reference to Figures 3, 5 and 13. Extended at the frontend of the machine beyondthe table 13 is a second table 20, supportedupon a standard 21 which may rise from the base 9. On this table 20 andnear the end of the table 13 is a I vertically extending, supportingbracket 22 which carries and supports an inwardly opening, ill-shapedclip 23. The upper and lower layers 2 and 3 of the incoming strip A arefed between the arms of theclip 23 and, as before stated, over and underthe spreader block 19. When the compressed springs is pushed into thefolded fabric between the laps 2 and 3 thereof, the clip 23 holds theparts together against the expansion tension of the spring, as clearlyshown on Figure 13. Two pairs of rotatable rolls 2 1,25, having engagingpins or teeth, located near either side of the spreader block'19,engagethe folded fabric and hold it inproper position over the spreader block19. a

Spring compreasion.-$Feferrin now more particulary to Figures 1314 and15, it will be seen that the compression of the spring S is effected bythe following mechanism: The tube T is provided with diametricallyopposite, longitudinally disposed slots 26. @n' each side of the tube Tand adjacent to said slots 26 is a rotatable shaft 27, each carrying acam 28. Un each side of the tube T, and in operative position to beengaged by the cams 28 are the'arms 29, each pivoted at its upper end at30 ton vertically movable bar 31, which moves in guides 31'. When thearms-31 are in their uppermost orraisedposi-' tion, the lower ends ofthe arms 29 are in the position shown on Figure 141;, having been forcedinto this position by the action of the cam 28, engaging lugs 32 on theoutside of the arms 29. The lugs 32 on the arms 29, when I in contactwith the cam28, function to quickly force the lower endsofthe arms 29into the slots 26, so that the spring S Wlll beneaaaai held up andprevented from falling to the bottom-of the tube T until thepredetermined time. The lower portion of each arm 29 has afootpiece orflange 33 of a width sufficient to enter and to slide vertically throughthe elongated slots 26 of tube T, and of a length sufiicient to enterinto the interior of the tube T when in the position shown in Figure 14,whereby the flanges 33 will engage a severed spring and hold it upwardlywithin the tube T. When the shafts 27 rotate the cams 28 to a certainpoint and release the arms 29, and the bar 31 is moved downwardly (ashereinafter explained), said arms 29 move downwardly also, andthe'flanges 33 thereon push the next subjacent spring downwardly untilsaid spring is in the compressed position shown in the bottom of thetube T on Figure 15. Tn said Figures 13, 14 and 15, the spr ng S, asformed and about to pass through the funnel 15, is given a separatedesignation as S and said spring will be held up in the upper part ofthe tube T by the flange 33 as indicated 'on Figure 14. The spring compressed is given the designation on Figure 15,

of S and the spring next to be compressed is given thedesignation S. Inother words, when the spring S is moved away the spring S isnextcompressed and the spring S drops a upper part of the frame B, arotatable shaft 34 carries a gear 35, the outer face of which isprovided with a cam 36. The short arm of a rocking lever 37 is inoperative engagement with the cam '36, the lever 37 being fulcrumed at38 to a supporting bracket 39 on the frame B. The longer arm of thislever 37 bears against an antifriction roller 40 mounted at 41. in theend of a plunger rod 42, which latter ismovably positioned upon thetable 13. The lower partof the tube T is provided with diametricallypositioned apertures 43 of sufficient size to permit the end of theplunger rod 4:2;when actuated, to pass through one aperture 43, contactwith the compressed coiled spring S and push the latter bodily ahead ofit through the other opening 43 between the separated laps 2 and 3 ofthe fabric as before explained. The

ment of the plunger places the spring 44:

under sufficient tension to cause the prompt return of the plunger toits normal position where its end will be ready to engage the springnext compressed in the tube T.

Gripping and feeding m o ement.-The feeding of the fabric strip throughthe machine is accomplished by step movement through a pair of grippingjaws, which take hold of the spring filled pocket and by bodilymovement, transversely of the machine, carry the strip longitudinally apredetermined distance; 1. e., a distance equal to the width of thepocket, so as to bring the folded, spread apart folds 2 and 3 of thefabric into the proper position for a compressed spring to be insertedtherebetween. Then these jaws are opened. the fabric released, the jawsre- 1 7 turned to their initial position, ready to grip the fabriccontaining the next adjacent spring to repeat the operation. Thegripping jaws are positioned at one side of the clip 23, so as to takehold of the fabric strip with the compressed spring therein, and drawthe strip out away from the clip 23.

Referring more particularly to Figures 10, 11 and 12, Twill firstdescribe the gripping devices, which consist of two vertically movablejaws 46, 46, spread apart and fulcrumed at 47, 47, upon a standard 48.Between these normally to hold apart the gripping ends of the jaws 46.These ends 46 carry plates 50 sufliciently large in area to cover thespring of largest diameter that is to be used in making the strips. Theunder side of the plate 50 is provided with pins 51 adapted, when thearms 46 are closed, and the plates 50 embrace the folded spring-filledstrip, to prevent the fabric from slipping between the plates and tocarry the fabric with the plates and the jaws as the latter are movedbodily. The opposite ends of the gripping jaws 46 are spread apart andso shaped as to be operatively engaged by a plate 52 one end of which iswedge shaped, as indicated at 52 and mounted on the end of areciprocating member 53. When the wedge 52 is inserted between the jaws46, the tension of the spring '49 is overcome and the gripping plates50, 50, are brought together. When the gripping jaws 46 are movedtransversely of the machine, as hereinafter explained, the ends 01)-posite the gripping ends ride over the wedge :52 and'by the tension ofthe spring 49 are forced towards the flat plate 52, whereby the fabricstrip and spring are released and the gripping jaws may be returned totheir original position.

In Figures 10 and 12, the jaws 46 ave started to open, the spring S heldbetween the plates 50 has been partially. released. Iii Figure 11 thejaws have entirely separated, the spring S has been expanded tocompletely fill the pocket and the mechanism is in position to be movedlaterally to the left hand, as shown in Figure 12, so as to repeat themovement as above explained.

Referring now to Figure 7, the reciprocating member 53 is actuated bythemove'ment of the rocking arm 54, fulcrumed at 55 upon a bracket 56,which extends out from the table 20. A reciprocating arm 57 is held uponthe under side of the table 20 by any convenient means, as for example,by a pair of downwardly projecting, spaced apart lugs 58 on the table20, the bar 57 being held in position by a cover plate 59. This bar 57carries on its short member 60 an adjusting screw 61 which latterengages one end of the rocking arm 54. The adjustment of the screw 61enables me to determine to a nicety the amount of lateral movement to begiven to the wedge 52 to open and close the aws 46.

The inner end of the bar 57 is adapted to be engaged by the cam surface62 on the face of the block 63, mounted upon a rotatable shaft 64.

WVhen the block 63 is rotated, the cam 62 pushes the bar 57 so that therocking arm 54 moves the wedges 52 inwardly against the tension of thesprings 65.

The table 20 is provided with an upwardly extending member 66 whichprovides means for supporting and forms a seat for the reciprocating bar53. One end of the springs is attached at 67 to the member 66 and theotherend of each spring is attached at 68 to the wedge 52 (Figure 4). Itwill be understood that when the rocking arm 54 moves the wedge forward,the springs 65 are stretched and put under tension, and when by therotation of the cam block 63. the end of the arm 57 is disengaged fromthe cam surface 62. the springs 65 very promptly pull the wedge 52 fromthe position shown in Figure 10 to the position shown in Figure 11, thusthe rocking arm 54 is reversed and the bar 57 returned so that its freeend may be engaged by the cam 62 for the next succeeding cycle ofmotion.

The gripping aws 46 and associated parts, however, have anothermovement, transversely of the machine, as stated, for the purpose offeeding the spring filled strip through the machine. ,This isaccomplished by the following means: The standard 48 is secured to aplate 69 from which depends a. pin 70. The plate 69 is held upon thetable 20 by a pair of L-shaped guide bars 71, as clearly shown inFigures 4, 7, 10 and 11. The table 20 is pro vided with an aperture 72,through which the pin 70 extends, said pin being of suflicient length toenter a recess or cut awayportion in the block 63 and to have its endengaged by and operated from the cam surface 73 which constitutes thebottom of the recess. It follows that when the shaft 64, carrying theblock 63, is rotated, the cam surface 78 will move the pin 70 andtherefore the plate 69 a distance sufiicientto bring the gripping jaws46 from the position shown in full lines to the position shown in dottedlines in Figure 6. The return movement fromthe dotted position to thefull line position is acc0mtceaati plished by the contracting of thespring it,

which at one end is secured at? to the plate the reciprocating. movementof the plate 69.

lln order to limit the extent of movement of the plate 69 in the guideways 71, the adjust ing screw 7 8 is mounted in a suitable aperture inthe table 20, its end extending into the aperture 7 2 so as to beengaged by the pin '10 and thus limit the movement in one direction ofthe plate 69. This arrangement permits of adjustment so the gri pingjaws will grasp a pocket and spring an move the strip a distance equalto the width of a pocket.

Sm ling mechanism-After the strip has been lled with springs, one ineach pocket, the intnrned edges 4: and 5 of the fabric and the springs Sare suitably fastened together. This may be done by stitching or byusing a hand staplinghimplement, but prefer to use conventional staplingmachines such asarc on the 'marketand available for such purposes. Twoof such machines are illustrated in Figure 4L, and desi nated as a wholeat 7 9,

80- The first stapleril'9 is located so as to be in the path of thestrip with springs in the pockets, adapted to engage the upperlap 2 andthe inturned margin 4 of the strip, and to all!) till inser the staple 8therein as shown in Figure 22, e other stapling machine 80 is on theopposite side of the strip A. In order to present the lower lap 3 to themachine 80, ll

locate the latter a sufficient distance from the stapler 7 9 to permitof twisting the strip half way round. This twisting takes place betweenthe twostapler machines at the broken awa part of the strip, asindicated inlFigure a. i. uch half-twistwill present the lower lap 3 ofthe strip uppermost so that stapler 80 may operate thereon upon theinturned margin 5 and lap 3. The staplers may be actuat ed by anysuitable mechanism. A double stapler, with its operating mechanismspaced a art the height of the strip, may be used in p ace of twostaplers.

Driving meoham'sm.ldeferring now to the mechanism for driving ortransmitting motion to the various parts heretofore referred to, thespring compressor arms 29 are recip rocated by the following. mechanism:--the belt 11 over pulley 12, mounted on shaft/10, driving the gear 81,which meshes with the pinion gear 82, through gear 83-, and gear 84 onshaft 85. The driven shaft 85 carries a arm. 87- adjustably secured inthe slot by means of a bolt and nut 88. The arm 87 is pivotallyconnected to a cross piece 89, which is connected at each end to one ofthe vertically movable bars 31 which travel in the guide ways 31 By thismechanism the compressor arms 29, pivotally connected to the movablebars 31, are given the reciprocating motion heretofore described. v

The horizontally arranged shafts 27, which carry the cams 28, are drivenby the following mechanism; a gear 90 on the shaft 10, meshing with gear91, through gear 92, on shaft 93, said shaft carrying gear 94 in meshwith gear 95, through two idler gears 96 to gear 97, on shaft 27.

The plunger 12 is reciprocated in a horizontal plane, as heretoforeexplained, by the action of the cam 36 in operative connection withlever 37. This cam 36 on the gear 35 is rotated by the belt 11, overpulley 12, on shaft 10, carrying pinion gear 35 which meshes with thegear 35 on the shaft 3 1.

The shaft 64 is rotated through pinion gear 82, meshing with gear 83 onshaft 98, carrying a sprocket wheel 99, sprocket chain 100, meshing withsprocket gear 101, on the stub shaft .102, through sprocket wheel 103,sprocket chain 104: to the sprocket wheel 105 mounted on the shaft 64:.

Counc l or-The shaft 64 carries a sprocket gear 106, which, in turn,works sprocket chain 107 which meshes with sprocket gear 108 on shaft109, mounted-on a standard 109, rotating the pulley 110, which carriesthe conveyor belt 111. This conveyor belt carries the spring strip tothe stapling device heretofore described.

It will be manifestthat the springs may be secured in the fabric pocketsby means other than the stapling devices described. For instance, asewing machine maybe used for this purpose.

It will also be obvious that the machine may be used for placing springsin the pockexample. 1 refer to astrip such as that shown in the MarshallPatent. No. 685,160.
